Been some discussion on FB group kz1300 oem/c about whether throttle cables are different lengths. From what I can tell, no they are not. They are identical. Bought some from Zed-Parts, and they are 60mm vs 72mm OEM as measured from ferrule end to cable ball end.
But both cables are same overall length with identical metal 'elbows' at throttle housing.
Zed-Parts, and two different throttle assemblies are all the same.. identical cable length.
Even though parts diagram show two different part numbers..
